In detail, for these video key frames of the intra-coded frames, we herein leverage a simple and effective object detection technique to help instantiate the static information of SSB. We integrate the recently proposed CenterNet [1]} in the encoder of our SSVC framework, which aims to locating objects and obtaining their corresponding class ID and spatial location (e.g., bbox) information in the feature domain. Then, we re-organize such features to form a part of SSB, by which some specific objects can be reconstructed and several image-based intelligent analysis tasks such as object classification/detection could achieve similar or better results than fully-decompressed images.
